Dear Macrumor members, I had some problems regarding my Hard Disk in a previous topic, I managed to fix the errors and format the drive. The disc seems ok but there is no OS on it. And when I boot (in verbose or single user mode) it keeps freezing on: Code: "Loading System\Library\Caches\com.apple.kext.caches\Startup\Extensions.mkext........................" Now this makes sense to me since the drive is empty but when I enter my Installation disc press ALT or C while booting it just freezes and does nothing. I see the CD next to my hard drive and nothing happens, anybody had this problem before? What should I do, it's just a 5 months old iMac from the latest generation :/.
